​
Describe your app

Open the editor at fastshot.ai and type a description of the app you want to build. Include:
  • Purpose — what the app does and who it’s for
  • Screens — list the main screens (home, profile, settings, etc.)
  • Data — what kind of data the app works with
  • Design — colors, style, mood (e.g. “dark theme with blue accents”)
Be specific. “A fitness tracker with workout logging, progress charts, and a dark theme” produces much better results than “make me a fitness app.”

​
Optional: add visual context

You can attach additional context to your first message:
  • Reference images — upload screenshots or mockups to guide the design
  • Website URL — paste a URL and Fastshot will analyze the site’s design, colors, and layout to inspire your app
  • Moodboard images — upload photos that capture the aesthetic you want

​
What happens next

After you send your description:
  1. Clarifying questions — the AI may ask 1-2 questions to understand your requirements
  2. Planning — architecture, screens, navigation, and a design system (colors, fonts, spacing) are created
  3. Code generation — production-ready React Native + Expo code is generated (about 5-7 minutes)
  4. Live preview — a working preview appears in your browser
You’ll see progress updates as each stage completes:
  • Setting up template
  • Starting mobile preview
  • Starting AI agent
  • Fine-tuning for your project

​
After creation

Once the preview loads, you can:
  • Test the app in your browser
  • Scan the QR code to test on a physical device with Expo Go
  • Send follow-up messages to make changes
Each project gets its own isolated environment with version control, so you can always roll back if needed.
